Abstract The thin film of ITO/PEDOT : PSS/PCPDTBT : PC61BM were fabricated and the effects of film-forming additives on the photoelectric properties of PCPDTBT : PC61BM were investigated. The results show that the film-forming additives results to a red shift of the absorption peak of PCPDTBTPC61BM active layer, substantially improvement of the performance of the solar cell. The existence of film-forming additives can lead to a nanoscale phase separation and increase of the contact interface between the donor and acceptor. The efficiency of photoinduced exciton separation, the carrier mobility and electrode collection charge carrier efficiency can be increased, thereby the device performances can be significantly improved by film-forming additives. Open circuit voltage of 0.66 V, short circuit current density of 10.42 mA·cm−2, fill factor of 0.38 and power conversion efficiency (PCE) of 2.64% were achieved under the condition of 100 mW·cm−2 air-mass 1.5 solar simulator illumination.
